M62 is at a distance of about 22,500 w:light-years from w:Earth and measures some 100 light-years across. From studies conducted in the 1970s it is known that M62 contains the high number of 89 w:variable stars, many of them of the w:RR Lyrae type. The globular also contains a number of w:x-ray sources, thought to be close w:binary star systems, and millisecond w:pulsars in binary systems.
